To all whom t may concern.-

Be-it known that I, BANIEL WADE Hazan- TINE, a citizen ot the United States, residin r at Conneaut, inthe county of Ashtabula an State of Ohio, have invented certain new and useful lm rovernents in Acetylene-Gas Generators, o ywhich the following is a speciiioation.

`This invention appertains to apparatus for enerating illuminatin gas from calcium carid, and has forits ob ect to devise a sim le mechanism which will admit of controlling the production of the gas, so as to prevent wastethereoi or the accumulation of dangerousressure within the generator.

T e ohiefobject of the invention is to prevent overproduction of the gas and to provide for automatic control of the same as consumed, also to admit of replenishing the carbidl from time to time as may be required, so as to supply the service-pipe With gas at all times an under pro erpressure.

The invention embo ies a generator and a combined pressure and reservoir tank, the latter being adjustable verticali to admit of regulating the pressure within t e generator, as may be re uired to meet existing conditions, and said tank also serving as an overflow or reservoir to contain Water or other liquidV which controls the production of gas according to the consumption thereof.

The invention also embodies novel means which Will admit of vertical adjustment of the canbid#receptaclex and seourance of' the same in the required adinsted position.

Fora full description of the invention andV the merits Ythereof and also to acquire a knowledge of the details of construction .of the means forefl'ecting the result reference is toheV had to the following descrip tion andE ae-V eom anying drawings.

liilethe invention may be adapted to different forms andfconditions by changes in the structure and minory details WithoutV de art mg from the spirit or essential features t tereof, still the preferred embodiment is shown in the accolnpanfingV drawings, in Which- Figure i is aV vertical central section` of enV acetylenesas generator embodying the invention. ig'. 2 is an enlarged sectional View of the cap for'closin tlieoV enin inthe top of thel genera-tor and rom "ch t `e carbid-receptacle is suspended, showing the means for Y teeth of said'A sides of the framewor holding the latter in an adjusted osition.

3 is a transverse section onthe l ne :no: of" Hg. 2.

Corresponding and like parte are referred to in the ollowin vdescription and indicated in all the views o the drawings by the same reference characters.

The machine or apparatus embodies two tanks 1 and?, the lat't'er'ljein the generator and the former the combined pressure and reservoir tank. The tank 1 is located at a hi lier level than thetank or generatorl in orer to provide ani le head for the Water, whereby the gas in t e tank 2niay be under sufficient pressure to cause it to ilow through the service-pipe to the outlets thereof; A pipe 3 connects the lower portion of the tank 1 with the lower portion of the tank. 2, and said pipe connection 3 is preferably extensible, being composed olV telescoping sections, which admit of'vertioalfadjuetrnent of the tank lfto Vary the pressure within the generator to moet varying conditions. A suitable peeking or stufiing box 4' is provided' :to maintain a tight joint between theA teleh Y scoping sections, so as to obviate leak. or Waste. V...The tank 1 is adaptedl to beraisedor lowered and supported in the adjusted positienrhg;V Yany Vsuitable means. For convenience, the framework 5 is su plied with an 'adjnenrliijesnp ort 6 upon'- Wliieli the tank I reste. VVl'lliesl es of the framework 5 are vertiealytootlied, andthe support niayloe adjusted'by bein Yplaced. uponcorres on'din r` 5 in a. manner which will be readily apparent. A cock 7 is interposed in the lengt ofthe pipe connection 3 to control communication lietween tlle two tanks. rlhe bottomrporton: of

the tank 2 is preferably sie ed? to a central point at which an opening'f's. orxneclx and: normally closed by means o-a cook 8. Thiscon'- structionV admi-te @fall sediment gravita-tin to a centralpoint and aciiitateecleanngjo the tank or enerator 2 whenV re aired. A screyrap; Se osos an openin in t p e head? or upperend ofthe tank 2, an the. caf-rhid-receptaoleY in' isY suspendedV therefrom in any manner. A handle 11 isa, pliedfothe screw- ,cap 9 for convenience oipturningl the same when tightening or loosening the cap.. The

handle 1i is spaced from thocatio-admit of the handE obtaining a Hrm an convenient IOC grip thereon and is connected at its inner end l with a boss 12, projected upward from the center of the cap.

The carbid-receptacle 10 may be of any formation so long as it is adapted to receive and hohl a quantity of' calcium carbid and admit of water having free access thereto. The receptacle is generally constructed of wire, although it may be formed of mashed or reticulated material of any kind. A connection 13 holds the carbid-receptacle 10 in suspension from the cap 9 and preferably consists of a stout wire or light rod, the same being attached to the parts in any manner. To admit of vertical adjustment of the carbid-receptacle to vary its position with referencc to the level of the water within the tanks 1 and 2, it is preferred to have the connection 13 adjustable with reference to the cap 9, and for this purpose said cap and boss 12 are vertically apertured to receive the rod or wire 13, which is held in the desired position by means of a tapered key 1-1, fitted into a tapered opening formed transversely in the boss 12 and intersecting with. the vertical opening through which the connection 13 passes. A packing 15 provides a tight joint between the connection 13 and the cap E) and is fitted` into an undercut recess formed in the lower side of said cap` as shown most clearly in Fig. 2.

The service-pipe 16 connects with the upper portion of the tank or generator 2 and is provided with cocks 17 and 18, the latter being located at a point between the generator or tank 2 and the cock 17 to admit of venting the generator as well as providing for4 the admission of air under pressure when it is required to force all or nearly all the water from the tank 2 into the tank 1 preliminary to replenishing the carbid-receptacle or withdrawing the sediment from the tank 2.

When starting the machine, the cock 7 is closed and a quantity of water is supplied to the tank 1 sufficient to fill the tank 2 to a depth to cover the carbid-receptacle 10. The receptacle 10 after being filled with calcium carbid is placed in position in the tank 2, and said tank is closed by screwing home the cap 9, after which said carbid-receptacle is adjusted to the desired elevation by moving the connection or rod 13 Vup or down within the boss 12 and securing it in the adjusted position by means of the key 14. The cock] 7 is closed and the cock 18 opened, and upon opening the cock 7 water will pass from the tank 1 'mto the tank 2. After reaching a level to cover all or a part of the carbid-receptacle gas will be evolved by the chemical action of the water and calcium carbid, and after the air has been expelled from the generator and the gas appears at the cock 18 the latter is closed, and the gas accumulating in the upper portion of the tank or generator 2 exercises a downward pressure upon the water therein and causes the saine to recede and pass into the tank 1, leaving the carbid-receptacle clear of the water. Upon opening the cock 17 the acetylene gas passes freely into the servicepipe and. may be burned at any outlet thereof in the manner well understood. As the pressure within the upper portion of the generator or tank 2 decreases by reason of consumptionof the gas the water will rise in said tank 2, passing therein from the tank 1 until it reaches the carbid-receptacle and again acts upon the carbid,whcn a fresh, quantity of gas is produced and the action. just described repeated. The initial head or pressure of the water contained in the tank 1 may be regulated by raising or lowering said tank, and provision is had for the vertical adjustment of the combined pressure and reservoir tank by means of the extensible pipe connection 3. The quantity of gas contained in the generator may be governed by moving the carbid-reeeptacle 10 up or down in the manner stated. The adjustment vertically of the carbid-receptacle incidentally provides for varying the pressure of the gas to a limited extent, as will be readily comprehended. After the carbid has become spent or unfit for further chemical reaction the cock 17 closed and a force-pump fitted to the cock 18, which is then opened and air forced into the tank 2 to create a pressure therein suflicient to force the water therefrom into the tank 1, after which the cock 7 is closed and the screw-cap 9 and carbid-receptacle 10 removed. Should it becom'e necessary te remove any sediment or to clean the generator, the cock 8 is opened and the residue or precipitate drawn eff. After the carbid-receptacle has been replenished and the parts replaced the cock 7 is open, and water asses from the tank 1 into the tank 2 unti the carbid-receptacle becomes submerged, and the carbid contained therein being acted upon by the water evolves gas, which displaces the air, and after said gas appears at the cock 18 the latter is closed and the operation hcreinbcfore repeated.

Having thus described the invention, what is claimed as new is- 1. In an acetylene-gas generator, the combination of a generator-tank provided with a carbid-receptacle, a vertically-adjustable pressure and reservoir tank normally arranged at a higher level than said generatortank, and an extensible valved connection between the lower portions of the two tanks, said connection being composed of telescoping sections having a stuffing-box or packing between them to obviate any possible leak.
